Male Reproduction Aaron, Keiah, Ryan

Male Anatomy Terms Vas deferens: The tube that connects the testes with the urethra. The vas deferens is a coiled duct that conveys sperm from the epididymis to the ejaculatory duct and the urethra. Erectile tissue is tissue in the body that can become erect, usually by becoming filled with blood. In males the urethra is a channel for semen during sexual intercourse. Scrotum is part of the males body located behind the penis and is a sac that contains the testes, blood vessels and part of the spermatic cord. Epididymis: A structure within the scrotum that is attached to the back side of the testis. The epididymis is a coiled segment of the spermatic ducts that stores spermatozoa while they mature and then transports the spermatozoa between the testis and the tube connecting the testes with the urethra (vas deferens).

Male Anatomy Terms Bulbourethral gland one of two small exocrine glands located on each side of the prostate. Bulbourethral glands secrete a fluid component of the seminal fluid, can also be called Cowper’s Gland. * They’re the same as the Bartholin Gland in females* As part of the male reproductive system, the prostate gland’s primary function is to secrete a slightly alkaline fluid that forms part of the seminal fluid, a fluid that carries sperm The testes are responsible for making testosterone, the primary male sex hormone, and for generating sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubes are responsible for producing sperm cells. ejaculatory duct is formed by the union of the Vas deferens with the duct of the seminal vesicle. They pass through the prostate and open into the urethra at the seminal colliculus.

Male Anatomy Terms The seminal vesicles are sac-like pouches that attach to the vas deferens near the base of the bladder. The seminal vesicles produce a sugar-rich fluid (fructose) that provides sperm with a source of energy and helps with the sperms’ motility (ability to move). The fluid of the seminal vesicles makes up most of the volume of a man’s ejaculatory fluid. seminal colliculus an elevated portion of the urethral crest upon which the two ejaculatory ducts and the prostatic utricle open.

Pathway of sperm

Pathway of sperm The testes are where sperm are manufactured in the scrotum. The epididymis is structure topping the testis, and it receives immature sperm from the testis and stores it several days. When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra.
